For Mac OS I would recommend trying GraphicConverter http://www.lemkesoft.de/en/products/graphicconverter/There is a free trial. It has an image browser which lets you modify EXIF data (and more) for selected images, and also has a batch convert with tons of options.

I don't use it a lot since I got Aperture, but for converting and browsing images which I do not want in Aperture, it is still my preferred choice.

A little compilation of a singing male skylark. This is pushing the 2x extender past its comfort zone, but thankfully the bird stayed mostly in one place (although pointing straight up and holding still with this setup has taken a bit of practice! ). 5DIII + 500L II + 2x III (f/10, 1/2500, ISO 2500).

Very nice. I always liked larks, but sometimes they are hard to spot (at least the ones in Europe that I know).

I guess that camera and lens weight was fully resting on your face when you took these?

Thanks, I appreciate these tips very much, I have a Mac book pro, and will be needing apperature I suppose. I have a great deal to learn, but can't wait to get rolling, I will be heading to Bedfords Camera shop monday in Oklahoma City.

One minor suggestion - I don't think that many would argue that Lightroom isn't the better option over Aperture at this point. Unless you have a specific reason for wanting Aperture, I'd go with Lightroom (there are some good deals out there at the moment for the standalone version if you don't want to go the subscription route). I should also say that you don't "need" either when just starting out. Your camera will come with software to allow you to do basic processing of RAW files and preparation for web or print - Lightroom will come in very handy once you need more convenient editing and catalog management tools.
